[Qemu-devel] [PULL 14/27] timer: update comments

[Michael Tokarev]

From: Cao jin <address@hidden>

The comments is outdated. The patch has following changes:
1. tense correction.
2. all clock time value is returned in nanoseconds, so, they are same in
precision.
3. virtual clock doesn't use cpu cycles.
